Volume ray casting, sometimes called volumetric ray casting, volumetric ray tracing, or volume ray marching, is an image-based volume rendering technique. It computes 2D images from 3D volumetric data sets. Volume ray casting, which processes volume data, must not be mistaken with ray casting, which processes surface data.

Famous quotes containing the words volume, ray and/or casting:
“Thy commandment all alone shall live
Within the book and volume of my brain
Unmixed with baser matter.”
—William Shakespeare (1564–1616)
“A small voice issued from a bed placed in utter darkness where no ray of light was admitted, complaining of bad nerves, low spirits, and terrible dreams.”

Todayness that the sunlight reproduces
Faithfully in casting twig-shadows on blithe
Sidewalks. No previous day would have been like this.”
